The assumption that we have an overall irqs_pending flags, and a one-to-one lguest <-> task mapping fails to hold on x86_64, where we can have multiple puppies, aka vcpus. Although ifdefs could be used, it makes the code much more unreadable, and other ports are on the way, anyway. So some sort of acessor is preferred anyway. Signed-off-by: Glauber de Oliveira Costa

plain text document attachment (lguest64-debug-utils.patch) This patch contains some nice features used to debug the lguest64 guest. It has a way to print page tables for either the host or the guest. It incorporates kallsyms, and can do a nice back trace of a guest when it crashes. The guest needs kallsyms obviously compiled in. Note: This code needs to be fixed to be more secure! Implements

From: Rusty Russell <rusty@rustcorp.com.au> lguest is a simple hypervisor for Linux on Linux. Unlike kvm it doesn't need VT/SVM hardware. Unlike Xen it's simply "modprobe and go". Unlike both, it's 5000 lines and self-contained. Performance is ok, but not great (-30% on kernel compile). But given its hackability, I expect this to improve, along with the

Hi all! Lately, Glauber and I have been working on getting both paravirt_ops and lguest running on the x86_64. I already pushed the x86_64 patches and as promised, I'm pushing now the lguest64 patches. This patches are greatly influenced by Rusty Russell, and we tried to stay somewhat consistent with his work on the i386. But there are some major differences that we had to over come.

Support the new CCW_CMD_SET_VQ format for virtio-1 devices. While we're at it, refactor the code a bit and enforce big endian fields (which had always been required, even for legacy).
